Connecticut’s Luxury ZIP Codes Surge: Where the Price Ceiling Keeps Rising

October 2025 | Market Insights | Presented by ReadySetLoan™️


A New Level of Luxury

Connecticut’s luxury market is rewriting the record books. For the first time, seven Connecticut ZIP codes now rank among the most expensive in the nation — and every single one of them lies within


Fairfield County.

These elite pockets represent some of the most desirable communities in the Northeast, defined by high-end amenities, coastal access, and a deep bench of cash buyers.

Here’s where Connecticut’s top-tier housing heat lives:

🏡 06878 – Riverside (Greenwich) → Median sale price: ~$2.75 million

🏡 06870 – Old Greenwich (Greenwich) → Median sale price: ~$2.65 million

🏡 06830 – Central Greenwich → Median sale price: ~$2.5 million

🏡 06831 – Backcountry Greenwich → Median sale price: ~$2.3 million

🏡 06840 – New Canaan → Median sale price: ~$2.2 million

🏡 06853 – Rowayton (Norwalk) → Median sale price: ~$2.1 million

🏡 06880 – Westport → Median sale price: ~$2.0 million


Together, these seven ZIP codes give Connecticut the third-highest number of luxury ZIPs of any U.S. state — trailing only California and New York.


What It Means for Connecticut Buyers & Sellers


For Buyers:If you’re shopping in Fairfield County’s luxury corridor, be prepared — prices have crossed new thresholds. Even outside the top seven ZIP codes, ripple effects are pushing up values in towns like Darien, Wilton, and Weston.


For Sellers:Listing in or near one of these elite ZIPs means opportunity — and expectation. Luxury buyers are looking for turnkey properties, lifestyle access, and value that matches the price tag. Strategic pricing and polished presentation are key.


For Investors & Developers:These ZIPs are more than status symbols. They’re demand indicators that reveal where capital, migration, and inventory pressure are heading next. Adjacent markets often see lift from these high-end clusters — especially where land and permitting allow for expansion.
